I'd start with repeated soaking with WD-40 or other penetrants.
Are you a saltwater boater?
Is the light pole an OEM part? Maybe the metals are dissimilar and with some saltwater and electrolysis have started bonding.

yep saltwater is the culprit and no not OEM so you are probabaly right...the pole is a tempo replacement out of aluminum. Were the OEM stainless?

Do like jimh suggests and put some penetrating oil on it like WD-40. An even better product fro freeing up stuck parts is Aero-Kroil.
The Whaler stern lights I have owned (the newest was a 1981) had poles made of chrome plated brass. Others here have reported that their's are made of stainless steel. Most after market lights have aluminum poles like yours and this will react badly in salt water in the chrome plated bronze fittings.

Check with the resistance between the two leads to the lamp and the pole metal. If there is any connection of the electrical circuit to the pole metal that would tend to create more problems with corrosion/electrolysis.

You should not use an aluminum light pole in BW's fittings, as you have learned. BW's poles are all SS. That's why they are so costly. I think you can buy the raw SS tubing, and rig this up yourself.
